Industrial Adhesives/Sealants for Motor Vehicle Powertrain

More complex designs have resulted in improved powertrain performance including fuel efficiency and reliability. To meet manufacturing requirements, epoxy, silicone and UV/visible light curing formulations have been developed that offer enhanced capabilities and speed productivity. Significant progress in gasketing, impregnation, bonding and potting has been achieved for automotive assembly applications.

One and two component potting compounds are available for applications in ignition coils, electronic control units, transmission controllers, sensors/connectors. They protect engine components against harsh environmental exposure. Special grades are thermally conductive and have superior heat dissipation properties. Additionally UV cure systems cure rapidly, require no mixing, have “unlimited” working life and have gained popularity because of the need for increased productivity.

These single and two part systems can be robotically dispensed and are used by automotive OEM's, tier one/tier two suppliers for high volume production operations. They feature superior flexibility/elongation, absorb shock/vibration, adhere well to metal/engineered plastics and have rapid cure cycles. Precise, consistent automated dispensing increases productivity/part quality, decreases material consumption and eliminates the need for manual labor-intensive manufacturing activities.

Self leveling systems fill small voids and channels. Paste viscosity materials stay in place and maintain their position/size until parts assembly. Solvent free, non-corrosive formulations are engineered to offer excellent compression set performance and exhibit extended service life.
